An intrusive igneous rock similar to granite, but containing more plagioclase than potassium feldspar.
Of the high-silica, coarse-grained, quartz-rich igneous rocks, granodiorites are quantitatively the most important.
2009, George Rapp, Archaeomineralogy, page 51:The dominant intruding rocks into the metamorphosed rocks of the Oban massif are granodiorites (Fig. 1).

Srivastava, editors, Magmatism in Relation to Diverse Tectonic Settings, page 346:Most of the rocks in the calc-alkaline association are granitoids, that is they are granites, granodiorites and tonalites all containing >20% quartz, with feldspar, mica and amphibole in various combinations (Chapter 3, Figures 3.10 and 3.11).
